# fpGetSubFileMetadataList()

Containers can store metadata about their subfiles that is independent of the metadata stored within those subfiles. This function allows you to retrieve the metadata stored within the container about a particular subfile.

## Syntax

    KVErrorCode pascal fpGetSubFileMetadataList(
        void* const pFile,
        KVGetSubFileMetadataListArg args,
        const KVMetadataList** const ppMetadataList);

## Arguments

`pfile` | The identifier of the container file - a file handle that you obtained by calling fpOpenFile().
`args` | A pointer to a KVGetSubFileMetadataListArg structure, which specifies how to retrieve the subfile metadata.
`ppMetadataList` | A pointer to a const KVMetadataList pointer. On success, this will contain the functions for accessing metadata elements, and must be freed with its fpFree() function.

## Returns

The return value is an error code.

## Discussion

Before retrieving any subfile metadata, you must get the main file information by calling fpGetMainFileInfo().

You must free the KVMetadataList pointer using its fpFree() function.
